ABB MP0A-AE2 Programmable Relay Module For Industrial Automation

ABB MP0A-AE2 is a compact interference protection module designed for 110–220 V AC coil circuits in industrial automation. As part of ABB’s MP0A family, the MP0A-AE2 acts as a surge suppressor for contactor coils, absorbing inductive transients when the coil is energized and de-energized and helping protect control electronics from spikes. The device is cataloged as MP0AAE2 with ABB part number 1SAL100545R9906, and distributors such as Proax and Rexel list it specifically as a surge suppressor for 110–220 V AC coil applications. Typical installations include control panels and machine systems where ABB contactors are used, providing a compact solution to meet interference protection needs in coil-driven circuits, and it is designed to integrate with ABB’s automation ecosystem. The MP0A-AE2 is referenced in ABB documentation and distributor catalogs as a dedicated 110–220 V interference protection module that complements MP0A-based protection in industrial control setups.
